See, I totally had a different take on the scene. I didn't think Everett was proud of Chad at all. I thought he was mocking Chad's pride in what he did, particularly with the snarky remark about why would Abigail be upset by what Chad did. It was clear to me that Everett was not happy about things at all.

Agreed. It was pretty clear that EJ Everett was mocking Chad for being so proud of what he had done when Chad had pissed off a lot of his friends. EJ Everett wasn't proud of him, he was essentially telling Chad he as an idiot.
